Answer: 78 problems
Step-by-step explanation:
Let x = the total number of problems that Joe started with. Joe finished half of his homework questions at school. This means that he finished 1/2 × x = x/2 of the home work at school. What he has left is x - x/2 = x/2.
He completed one-third after practice. This means he completed 1/3 × x = x/3 after practice The number of problems left altogether would be total number of problems - the the sum of the amount he finished at school and the amount he completed after practice. It would be x -(x/2 + x /3) = x - 5x/6 = x/6
If he has 13 to more to finish, that means
x/6 = 13
x = 13×6 = 78 minutes
<u>To find the cost of Senior T-shirts needed, </u><em>Multiply (the number of students) by (how much each T-shirt costs).
</em>
350 × 7.2 = $2520
<u>To find the cost of the yearbooks needed,
</u><em>Multiply (the number of students) by (how much each yearbook costs).
</em>
350 × 24.75 = $8662.5
<u>Now, find the TOTAL money the Student government has to pay.
</u><em>Add up the two sums.
</em>
2520 + 8662.5 = $11182.5
<em><u /></em>
<em>SO, the answer is
</em>
<u>$11182.5</u>

Hopefully this helps, Idk how well to explain it but Im pretty sure its C if not tell me! :)
Based on the fact that Steve was originally driving the speed limit and then stopped a few hours and drove slower, the situation models a piecewise defined function.
<h3>What is a piecewise defined function? </h3><h3 />
This is a type of function where there are two or more parts joined together. In other words, there are two equations to represent the different parts of the function.
In this case, Steve was driving at a certain speed. This is one function. Then he stopped for a couple of hours which is another function. Then the last function has him driving slower than the speed limit.
In conclusion, this is a defined piecewise function.
